Access to Power BI report without authenticating with microsoft power BI account

Hi,

I have a .Net Core/Angular application.

In it i have some Power BI reports, for now the user needs to autheticate to the website and then also he needs to sign in with his Microsoft Power BI account (with a permission to see this exact report) to see the report (if not already signed in).

Can i add some code so the user will be signed in automatically to an account chosen by me when authenticating to the web Site or can i add some sort of filter to the link of the report to do this?

I'm using the iframe to show the report for sure.

Any help? and thanks.
